             * Right, this is really confusing and there is a lot of maths going on here

             * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
             *
             * Solution:
             *
             * We assume the radius of the polygon is half the size of the canvas at first
             * at each index we check if the text overlaps.
             *
             * Where it does, we store that angle and that index.
             *
             * After finding the largest index and angle we calculate how much we need to remove
             * from the shape radius to move the point inwards by that x.
             *
             * We average the left and right distances to get the maximum shape radius that can fit in the box
             * along with labels.
             *
             * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
             * on each side, removing that from the size, halving it and adding the left x protrusion width.
             *
             * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
             * and position it in the most space efficient manner
             *
